Design of a 1-MW CW 8.5 GHz transmitter for planetary RADARA proposed conceptual design for increasing the output power of an existing X-band planetary radar transmitter from 365 kW to 1 MW CW is discussed. The paper covers the basic transmitter system requirements as dictated by the specifications for the radar. The characteristics and expected performance of the high-power klystrons are considered and the transmitter power amplifier system is discussed. Also included in the discussion is the design of the exiter system. Two alternative feed systems for delivering the 1-MW CW signal to the antenna system are described. The expected performance of the beam supply, heat exchanger, and monitor and control devices is also presented. Finally, an assessment of the state-of-the-art technology to meet system requirements is given and possible areas of difficulty are summarized.
